River Pollution
Scientists from the Environment Agency were called to
investigate a river.
Local fishermen reported that they had not caught trout in
the river at Pine Bridge for many months. There were more
algae growing in the river and it had a bad smell.
Scientists measured the oxygen levels in the water upstream and downstream
from Pine Bridge.The results are shown below.
